AMD Ryzen 5 1600X & 1500X Performance Review
Overclocking Results – Hitting A Wall…Again
Back in the Ryzen 7 1700X and 1800X reviews I took no small amount of time discussing how Ryzen behaved when overclocked. Both of those processors basically topped out at about the same point as their bigger brothers.
It seems like these Ryzen CPUs or their motherboards have a hard limit that cuts off chip current at a certain power consumption level. We’ve talked to various contacts and this seems to be a failsafe that may be modified as AMD rolls out new microcode for Ryzen processors. Until then, 4GHz is still a very good result and it boosts performance significantly on both chips but right now, running into this wall over and over again has me pretty frustrated. Its obvious Ryzen has more gas in the tank that’s being left untapped. Hopefully this changes as the platform matures. So what did I hit…..you guessed it….
The 1600X sample I have in hand landed at just over 4GHz before the system simply cut off its power, leaving me with a black screen whenever load was applied. I could actually boot into Windows without a problem all the way up to 4.3GHz but that power limitation kept stepping in.
Unfortunately the 1500X was in the exact same position: 4Ghz or so. While this might seem disappointing, on a percentage basis these chips are actually quite decent overclockers and the performance they can deliver with higher frequencies is impressive to say the least.
